lights flashing after shutdown

[GerryGarnto]

After shutdown, the power and activity lights on the front of my PC flash in sequence until startup/power on. They flash 4 times, pause, and flash again; over and over.

Is the internal battery going bad?

Greetings,

Welcome to the forum.

I am not a HP employee.

The forum needs a HP product number to assist.

Hi GerryGarnto,

Thanks for the product number.

The troubleshooting guide can be reviewed at this (Link).

Look at page 58 for possible causes.

Well, according to the PDF and link to HP supported products, my PC is not on the list (Win-10). They have a section prior to 2013, but I don't think mine is that old. This is one I got 'off-lease' through TigerDirect in 2015, with Win-7 Pro installed. I upgrade when Win-10 was offered.

My front panel LCD lights are green, and there's no peeps. Just flashing in 4-sequence, then a pause. It didn't start doing it until I reset defaults because I kept getting the "Uncorrectable Error" panes. And those errors didn't start until I allowed my employer's IT guy access remotely for 'support' with one of their web pages.

I have a newer PC /Win-10 in box. It'd just be simpler to pull this hard drive, and set up a new PC.

Thanks for the assist.
